All the resistor are connected in series.so,
- Combined resistance (R) = 0.2 + 0.3 + 0.4 +0.5 + 12
- Combined resistance (R) =13.4Ω
- Potential difference (V) = 9 v
- Current (I) = ?
Current flow through the whole circuit can be calculated by using ohm's law:-
Since the same current flows through all the resistors connected in series in a circuit,therefore 0.67 ampere of current would flow through the 12Ω resistor.
